Adrian Quaife-Hobbs became the first ever driver to win both races at an Auto GP round and broke the record for the number of wins in a season with a drive from eighth to first in the second race at Portimao.
After winning Saturday's race, the Kent-born driver started from eighth on the reverse grid but jumped up to fifth with a good launch. He got by Sergio Campana for fourth before the end of the lap, at which point the safety car came out to recover the car of Quaife-Hobbs' main rival Pal Varhaug following a collision with Sergey Sirotkin.
Soon after the restart the safety car was back out after series newcomer Juan Carlos Sistos ran into Quaife-Hobbs' Supernova teammate Victor Guerin. With the entire field having made their mandatory pitstop, Quaife-Hobbs was third at the restart behind the Manor MP duo of Chris van der Drift and Daniel De Jong.
He soon got past both and into the lead, which he stretched to five seconds by the flag. His fifth win of the season bettered the previous record set by Romain Grosjean in 2010, and put him on to 196 points, with Varhaug on 123 with just two rounds in Brazil and the United States remaining.
Van der Drift crossed the line in second ahead of Sirotkin who recovered from his first lap incident. Campana and Regalia were fourth and fifth ahead of Giancarlo Serenelli and De Jong.
